Abstract
Physical-chemical processes taking place in formation of particles of iron intermetallics based on Fe₃Al alloyed with Cr, Zr, Mg, La and Ti under mechanochemical synthesis conditions were investigated. It is determined that the process of synthesis of alloyed powders passes a range of sequential stages with formation of solid solutions and finishes with formation of single-phase Fe₃Al(Cr, Zr), Fe₃Al (Mg), Fe₃Al (mg, La) and (Fe, Ti)₃ Al products with nanodispersed structure (size of CSA = 10–30 nm). The powders are designed for deposition of heat-resistant FeAl-coatings using thermal spraying and electric arc metallizing methods. 12 Ref., 2 Tables, 10 Figures.
Keywords: iron-based intermetallics, alloying, mechanochemical synthesis, powders, structure, properties, thermal spraying
